# Millimeter of Water Column (mmWC) to Millimeter of Mercury (mmHg) Pressure Unit Conversion Calculator

This calculator allows you to easily convert pressure values from **Millimeter of Water Column (mmWC)** to **Millimeter of Mercury (mmHg)**, commonly used in meteorology, medical equipment, and low-pressure scientific applications.

**Definition: Millimeter of Water Column (mmWC)**

The **Millimeter of Water Column (mmWC)** is a unit of pressure that represents the force exerted by a 1-millimeter column of water at 4°C. It is typically used for measuring low-pressure differences in systems such as HVAC, water distribution, and other low-pressure industrial applications.

**Definition: Millimeter of Mercury (mmHg)**

The **Millimeter of Mercury (mmHg)** is a unit of pressure based on the pressure exerted by a 1-millimeter column of mercury at 0°C under standard gravity. It is frequently used in barometry, medical fields (e.g., blood pressure measurement), and vacuum systems.

**Formula for mmWC to mmHg Conversion:**

**Pressure in mmHg=Pressure in mmWC×0.0735559**

**How to Convert mmWC to mmHg: Example Calculation**

Suppose you have a pressure of **500 mmWC**.

To convert it to mmHg:

500×0.0735559=36.77795 mmHg

So, **500 mmWC** is equal to **36.78 mmHg**.

**Quick Reference Conversion Table for mmWC to mmHg**

Millimeter of Water Column (mmWC) | Millimeter of Mercury (mmHg) |

1 mmWC | 0.07356 mmHg |

10 mmWC | 0.73556 mmHg |

100 mmWC | 7.35559 mmHg |

500 mmWC | 36.78 mmHg |

1000 mmWC | 73.56 mmHg |

**Uses of mmWC to mmHg Conversion Calculator:**

**Medical Applications:**Convert pressure values for medical devices like blood pressure monitors, where mmHg is a standard unit.**Meteorology:**Useful for converting pressure readings in weather data between water and mercury columns.**Industrial Calibration:**Applicable for converting low-pressure values in laboratory equipment and process control instruments.

This **mmWC to mmHg conversion calculator** is an essential tool for professionals working in scientific, medical, and industrial applications where precise pressure conversions are required.
